Publication date: 2012
Publication number: CN102626611

Abstract: The invention provides a method for preparing a metal ion imprinting adsorbent with an underwater selective recognition performance. The method comprises the steps of: preparation of an amino functional material: dispersing a nuclear body material into a methanol solution, slowly adding 3-propylaminoethoxy silane, uniformly stirring, and then, continuously adding a cross-linking agent and a stabilizer to form the amino functional material; and preparation of the metal ion imprinting adsorbent: dispersing the amino functional material in the methanol solution, and exposing to ultrasound to obtain a solution A; dissolving isonicotinic acid and metal template ions in deionized water to form a solution B; dripping the solution B into the solution A, and reacting to obtain a white sol-like product; and eluting the metal template ions: performing Soxhlet extraction by using an acetic acid-methanol solution, then eluting the metal template ions by using a hydrochloric acid, and drying to obtain the metal ion imprinting adsorbent. The metal ion imprinting adsorbent disclosed by the invention can be widely applied to advanced treatment of drinking water as well as enrichment recovery or rapid analysis detection of metal ions in different water bodies, such as industrial waste water, aquaculture water and seawater.
